| X3741 To ROY{Sir Henry Royce}, from EFC. EFC5/T12.11.23. X.3741 - RUNBAKEN SYRINGE HYDROMETER. Herewith copy of my assistant's report on the test of this hydrometer. It is not considered that this hydrometer would be so suitable for a chassis purpose as the 'Perfection' or the 'Exide' we tested recently, though perhaps it has advantages as a pocket instrument. We therefore do not consider we have any further interest in this particular hydrometer. Hydrometer returned herewith. EFC. | ||
